This is a Brownie Scout Handbook from 1962.  This hardback book is in very good condition, it has the previous owners name on the inside cover, but I did not see any other markings in the book.
There is some wear to the corners and spine as expected.
Before you became a Girl Scout you were a Brownie, I remember being a Girl Scout and my sister was a Brownie, so maybe it was an age thing, not really sure.
